Unified database operations

Opyra

The "Buttery Smooth" Registry-Based ORM for Python.

Opyraa next-generation data layer built on top of msgspec. It unifies SQL (Postgres, SQLite) and NoSQL (MongoDB) under a single, ultra-fast, type-safe API using the Registry Pattern.

It eliminates "Global State" and "Boilerplate Fatigue" by using explicit Opyration registries and "Bound Instances" ("The Base").

🚀 Why Opyra

• Registry Pattern: Explicitly register schemas with an Opyration engine. No magic globals.
• Bound Instances: Objects know where they belong. user.save() just works because the user carries "The Base" (the engine reference).
• Dirty Tracking: Automatic change detection. Calling .save() only updates what changed (efficient UPDATE vs INSERT).
• Universal API: Switch from SQLite to Postgres to Mongo without rewriting your model logic.
• Blazing Fast: Built on msgspec (faster than Pydantic/JSON) and native async drivers (asyncpg, motor).

📦 Installation

pip install opyra

# Install drivers as needed:
pip install opyra[postgres]  # installs asyncpg
pip install opyra[mongo]     # installs motor
pip install opyra[sqlite]    # installs aiosqlite

⚡ Quickstart

1. Define your Schema

Inherit from Table (SQL) or Document (NoSQL). These are pure data structures (msgspec.Struct).

from opyra import Table, Document

class User(Table):
    id: int
    name: str
    email: str

2. Initialize the Opyration

Create an engine and register your models. This is your "Database Context".

from opyra import Opyration

op = Opyration("postgres://user:pass@localhost:5432/mydb")
op.register(User) 
# Now available as 'op.user' (snake_case automation)

3. Use it!

Factory Access (Creating Data): Use op.user(...) to create a "Bound Instance".

# Create alice attached to this engine
alice = op.user(name="Alice", email="[e-mail]") 

# Save detects this is a NEW record (no ID) -> INSERT
await alice.save() 
print(alice.id) # ID is auto-populated

Repository Access (Querying Data): Use op.user.find(...) to search.

# Find by ID
user = await op.user.find(1)

# Find by Template (Fluent API)
users = await op.user(name="Alice").find()

Dirty Tracking (Updating Data): Modify fields naturally. Opyracks changes.

user.name = "Alice Wonder"
# Save detects EXISTING record + Dirty Fields -> UPDATE users SET name='Alice Wonder' WHERE id=1
await user.save()

🏗️ Web Framework Integration

Opyradesigned for dependency injection.

# app.py
op = Opyration(os.getenv("DATABASE_URL"))
op.register(User)
op.register(Post)

# Inject into your app
app.keep('op', op)

# handling request
async def get_user(req, res, ctx):
    op = ctx.peek('op')
    user = await op.user.find(int(req.params['id']))
    res.body = user
